Camera compatibility guide

Connect a Grandstream GSC camera stream

Grandstream GSC product numbers cover different device types and firmware interfaces. The GSC3610, GSC3615, GSC3620 and GSC3565 camera examples below have documented network-video workflows. Do not assume that every GSC35xx or GSC36xx device has identical server settings.

Camera model and service settings matter

This page follows Grandstream camera manuals reviewed on 2026-10-18. These are documentation-based examples, not independently verified SmartRTSP physical-device compatibility results.

Documentation checked: 2026-10-18. This guide is not a physical-camera test or model certification.

GSC3610, GSC3615 and GSC3620 stream numbering

The cited camera manuals document /0 for the primary stream and /4 for the secondary stream. The secondary stream is not /1 in this documented workflow. Use the RTSP port configured on the camera and the device credentials required by its authentication settings.

rtsp://CAMERA_IP:RTSP_PORT/0
rtsp://CAMERA_IP:RTSP_PORT/4

GSC3565 has its own RTSP server switches

The GSC356x manual identifies RTSP server settings specifically for the GSC3565 and describes RTSP and ONVIF as disabled by default in that workflow. It documents authentication choices and an RTSP port setting. Do not transfer those defaults or menu locations to the older GSC3610 interface.

Enable only the services needed for your installation and retain authentication. Anonymous live viewing is not a prerequisite for adding a camera securely. An audio product that consumes an RTSP music stream is also not automatically an RTSP video camera.

Prepare a secure device account and feed

  1. Confirm the exact GSC model and open its manufacturer camera manual, not an audio-device guide with a similar prefix.
  2. Connect the supported network and power interfaces and find the camera local address.
  3. Sign in locally and set a unique password. Review whether the firmware uses device credentials or dedicated RTSP credentials.
  4. Enable the RTSP server if the model requires it, retain authentication and record the configured port.
  5. Select the enabled primary or secondary video profile and use the stream path documented for that model.
  6. Add the stream and local credentials in SmartRTSP, then verify the correct image and sustained playback on the same trusted network.

Troubleshoot authentication and encoding separately

Grandstream documentation illustrates credentials inside RTSP addresses, but credentials do not need to be published in examples or shared screenshots. Prefer separate account fields where the viewer supports them. If a URL must contain a password, reserved URL characters require correct escaping; an unescaped delimiter can change how the address is parsed.

If authentication succeeds but the image stays blank, check the selected video profile, codec and whether the requested stream is enabled. If discovery fails while a direct stream works, inspect ONVIF settings independently; it is a separate service. Receiving video does not establish PTZ, intercom, event or two-way-audio support. Check every required function against the exact device and receiving platform.

Check each feature independently

Start on the same local network with the exact model, firmware and account permissions. A working video stream does not prove support for ONVIF discovery, pan or tilt, two-way audio, events, or every recording feature. Test the features you need in your installed SmartRTSP app.

Keep camera credentials private. Do not expose camera ports to the public internet just to test local viewing. Manufacturer cloud accounts, device accounts and generated sharing links are not interchangeable.

Frequently Asked Questions

Which path is the GSC3620 secondary stream?

The cited GSC3620 manual documents /4 as the secondary stream. Use its configured RTSP port and required local credentials.

Should I enable anonymous viewing?

No. Anonymous access is not required for this guide. Keep authentication enabled and use an appropriately permitted local account.

Are RTSP and ONVIF enabled on every Grandstream camera?

No universal default is established. For example, the GSC3565 workflow has explicit service switches. Check the manual and current firmware for your model.
